Hi,

I am running a pseudo-live stream based on a playlist, [as described here](https://www.wowza.com/forums/content.php?427-How-to-do-scheduled-streaming-with-Stream-class-streams-%28application-module%29).

I have TTML files alongside the videos, and they are properly loaded & parsed by the “vodcaptionproviderttml” TimedTextProvider, however the caption data is never sent to my Flash clients connected over RTMP.

When I put a breakpoint inside ‘getLanguageRenditionAMF()’, you can see here that the TTML is being loaded & processed. In this image the ‘trackIndex’ is ‘99’, I also hit this breakpoint twice with the same data on trackIndex=2.

![](https://www.evernote.com/shard/s18/sh/b6a79bde-3084-4341-babf-dbec47823fea/3a603fb2bef7210cb429fb456c9f43e3/deep/0/Screenshot%209/26/13%203:08%20PM.png)

This is about as far as the provider gets. There are no calls to any of the other methods past that point.

I have added breakpoints & trace statements into my Flash client for the onTextData method, and it is never called.

Is there a configuration step I am missing?

Could this be because the Application/Streams/StreamType is set to ‘live’? Do I need to perform some trickery to get the VODTimedTextProvider to operate on a ‘live’ stream?

Thanks!

Chris
